I keep on getting a grabbing sound/feeling from the right rear of the car after I drive the car a while stopping and going. When I excelerate fast or slow I get a grabbing feel from the rear of the car. I changed the calibers and pads on both sides and even the rubber flex hose on the drivers side and it still happends. The emergency brakes don't work so I don't think thats the problem. It seems to happen only when the breaks heat up.
Please help me figure this out. It's getting to be a pain in the *ss.
Thanks
